i have an 89 rx7 with an apex seal bad and looking into an 88 turbo rx7 that the motor is good. how hard would it be too swap motors. the 89 is the better car but 88 has better motor. or would i be wasting my time.

 

Long story short: cross series swaps are a waste of time. The effort required is not worth the hassle unless the car is already wired with a standalone or you intend on making more then 400HP in a TII.
